There is one patch from Peng > Fan that already changed ipc.h. Hi Shawn, Please ignore 1/6 patch since it has been done with Peng's patch. I will resend flexcan patch set after Peng's patch goes into mainline. Could you please review 5/6 patch which is suggested by Flexcan driver maintainer? Thanks.
